> *Title:*  Learning Whenever Learning is Possible: Universal Learning
> under General Stochastic Processes
>
> *Abstract:*
> I will present a general theory of learning and generalization without the
> i.i.d. assumption, starting from first principles. We focus on the problem
> of universal consistency: the ability to estimate any function from X to Y.
> We endeavor to answer the question: Does there exist a learning algorithm
> that is universally consistent under every process on X for which universal
> consistency is possible? Remarkably, we find the answer is "Yes". Thus, we
> replace the i.i.d. assumption with only the most natural (and necessary!)
> assumption: that learning is at least possible. Along the way, we also find
> a concise characterization of the family of all processes that admit
> universally consistent learners. One challenge for learning is that some of
> these processes do not even have a law of large numbers.

> *Bio:*
> Steve Hanneke is a Research Assistant Professor at the Toyota
> Technological Institute at Chicago. His research explores the theory
> of machine learning, with a focus on reducing the number of training
> examples sufficient for learning. His work develops new approaches to
> supervised, semi-supervised, transfer, and active learning, and also
> revisits the basic probabilistic assumptions at the foundation of learning
> theory. Steve earned a Bachelor of Science degree in Computer Science from
> UIUC in 2005 and a Ph.D. in Machine Learning from Carnegie
> Mellon University in 2009 with a dissertation on the theoretical
> foundations of active learning.
